Data processing device including clock recovery from various sources

A data processing system, comprising:

• a first data processing device, including:
• a) a first receive data input unit for inputting a first receive data stream into the data processing device;
• b) at least one second receive data input unit for inputting at least one second receive data stream into the data processing device;
• and
• c) a clock recovery unit for recovering a clock signal from at least one of the first receive data stream and the at least one second receive data stream;
• d) a control unit for controlling the clock recovery unit as a function of one of the first receive data stream and the at least one second receive data stream;
• and
• e) a delay unit for delaying the at least one second receive data stream with respect to the first receive data stream in such a way that the first receive data stream is synchronized with the at least one second receive data stream;
• and
• a second data processing device connected in series with the first data processing device and including:
• a) a third receive data input unit for inputting a third receive data stream into the data processing device;
• b) at least one fourth receive data input unit for inputting at least one fourth receive data stream into the data processing device;
• and
• c) a second clock recovery unit for recovering a second clock signal from at least one of the third receive data stream and the at least one fourth receive data stream;
• d) a second control unit for controlling the second clock recovery unit as a function of one of the third receive data stream and the at least one fourth receive data stream;
• and
• e) a second delay unit for delaying the at least one fourth receive data stream with respect to the third receive data stream in such a way that the third receive data stream is synchronized with the at least one fourth receive data stream.

A method for data processing including clock recovery in a data processing device, comprising:

• a) inputting a first receive data stream into a data processing device using a first receive data input unit;
• b) inputting at least one second receive data stream into the data processing device using at least one second receive data input unit;
• c) recovering a clock signal from at least one of the first receive data stream and the at least one second receive data stream using a clock recovery unit;
• d) controlling the clock recovery unit as a function of one of the first receive data stream and the at least one second receive data stream using a control unit;
• and
• e) delaying the at least one second receive data stream with respect to the first receive data stream using a delay unit in such a way that the first receive data stream is synchronized with the at least one second receive data stream.
